The near-legendary original NiGHTS was released on the dear old Sega Saturn and came with one of the world's first analogue joypads. Its gameplay involved flying Harlequinesque character NiGHTS in a series of elegant loops and dives to eliminate enemies, fly through lines of hoops in the sky and pick up gems for higher scoring chains. The new version ought to be right at home on the Wii, with its pioneering, arm-waving control scheme, and indeed the levels that involve piloting NiGHTS, either to chase after a giant bird or score increasingly large chains to impress a blue octopus, work beautifully. Sadly, the other bits aren't nearly as accomplished, including those where you use NiGHTS to sweep up big blobs of water floating in the air or, worse, the ground-based platform levels, which feel like padding compared with the effortless grace of the flying sections. NiGHTS was always a quirky one, and so it remains in its latest incarnation.

From Japanese masters Hudson comes a very Japanesey, balls-out, side-scrolling shooter of the variety that was very popular in the 1980s. You fly with one stick and direct a relentless stream of digital destruction with the other, a familiar mechanic to the many fans of Geometry Wars or Smash TV. Everything has been pumped up to epic proportions, with vast powered-up ordnance creating even more screen-filling explosions and giant robotic beasts attacking from all sides, including the background. The two keys, as in most games like this, are to work out which weapon to collect when, and to learn the patterns of incoming enemies, who never deviate from their set routines. The other thing that feels distinctly old school is the savagery of its difficulty level and limit of two credits. Seeing even the end of level two will be a serious test.
